Yes, I love the idea of event/interrupt-driven DVFS and I agree with
the core idea. The remaining concern is that the current "implementation"
might be too invasive to the subsystem while it does not need to be as
a governor can always choose not to poll. And the other issues are
quite minor as well.
Actually, it appears that next-generations of some architectures
(I think I cannot publically say which and when) are going to support
this for general peripherals on the bus and the CPU soon.
Cheers,
